The first request for device rpc through the script after thingsboard is started is always timeout. about thingsboard

Found the problem, it is a bug of tb_device_http：

    
def send_rpc(self, name: str, params: dict = None, rpc_id: int = None) -> dict:
        endpoint = f'rpc/{rpc_id}' if rpc_id else 'rpc'
        return self._publish_data({'method': name, 'params': params or {}}, endpoint)

Here, when rpc_id is 0, the expected result will be exceeded.
